Figure 1 represents the profile of a transverse wave on a string (t = 0) in the positive X-direction at a speed of 20.0 m/s. a) Determine the wavelength and the frequency of this wave.
b) calculate the maximum speed of the string oscillates between the two amplitudes. name this type of speed

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?

An athlete performing a long jump leaves the ground at a 27.0 degree angle and lands 7.80m away. what was the takeoff speed?

Two wooden members of 80 × 120-mm uniform rectangular cross section are joined by the simple glued scarf splice shown. knowing that β = 22° and that the maximum allowable stresses in the joint are, respectively, 400 kpa in tension (perpendicular to the splice) and 690 kpa in shear (parallel to the splice), determine the largest centric load p that can be applied using mohr's circle. (round the final answer to two decimal places.)
